DEVICE FOR TILTING WAGON-BEDS.

SPECIFICATION forming part of Letters Patent No. 245,745, dated August 16, 1881. Application filed May 11, 18er. (Model.)

.To all whom 'it may concern Be it known that I, HENRY W. POWERS, of Pittsfield, in the county of Berkshire and State ot' Massachusetts, have invented certain new and useful Improvements in Devices for Tilting VVagon-Beds; and I do hereby declare that the following is a full, clear, and exact descriptionof the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part ot' this specification.

Figure l is a perspective view, Fig. 2 is a vertical sectional view, Fig. 3 is a side view, and Fig. 4 is a longitudinal sectional view, of the device in position for operation.

Corresponding parts in the several figures are denoted by like letters of reference.

This invention relates to an improved device to be attached to wagons for the purpose ot' raising or tilting the wagon-bed so as to unload the same when required, thus converting an ordinary wagon into what is generally known as a dumping-wagon and it consists in certain improvements in the construction of the same,which will be herein after fully described, and particularly pointed out in the cla-im.

In the drawings hereto annexed, A represents a hollow upright or standard provided upon its rear side with a vertical slot, B.

C is a rack-bar, sliding vertically in the upright A, and provided on one side with a lug, D, projecting through and sliding in the slot B, and having a pivoted shoe, E, bolted or otherwise suitably secured to the bed of the wagon, to which the device is attached.

The side of upright A is provided with laterally-projecting brackets F, having bearings Gr for a shaft, H, carrying a pinion, I, engaging the rack-bar C,and a ratchet-wheel,J, engaging a spring-pawl, K, pivoted upon `the side of a crank-arm, L, journaled upon said shaft, and a gravity pawl or dog, M, pivoted Y to the side of upright A.

The upright A is pivoted at its lower end to a shoe, N, which is in practice bolted or otherwise secured to the front end of the reach of and by reference to the drawings hereto annexed.

The upright A is secured by the pivoted shoe N to the reach of a wagon, and the vcrtically-sliding rack-bar C by the pivoted shoe E to the frontendof the wagon-bed. By working the crank L the shaft H and pinion I are rotated, thus raising the rack-bnr and tilting the wagon-bed, which may be held at any desired inclination or angle by the pawl or dog M engaging the ratchet-wheel. The device is simple, easily operated, and may be readily attached to any ordinarily-constructed wagon.

I am aware that rack-and-pinion and screw` threaded devices have been before used for similar purposes, and such constructions are not sought to be covered broadlyin this application. y

I attach importance to the pivotal connection with the wagon-body.

What I claim is- The vertically-recessed standard A, pivoted to the shoe N, and vertically-sliding rack C, pivoted to the body by means of shoe E, the shaft H, pinion l, ratchet J, crank L, and pawls K M, all constructed, arranged, and combined to operate as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

HENRY W. POWERS.
